Review: Good brand. - Has been in over a year and works well. I have this tied in with two smoke alarms and they all go off as they're supposed to when one does.
Review: Great CO detector - I was having problems with the hard-wired CO and smoke detectors in my home and was searching for replacements. In doing some online research, I ended up calling Kidde (pronounced kid-ah, I found out), and had a nice, long, informative conversation with a very pleasant lady in customer service. We discussed all the pro's and con's of various units, and these detectors sounded like what I wanted. My existing detectors were First Alert, so in order to install the Kidde detectors without doing some rewiring, I needed to get adapters, which convert the wiring harness plug from First Alert to Kidde. Unfortunately, I could not get these from desertcart. The only adapter they offered was a package of two, one of each type, so you had to use one and throw the other one away. And there was a 2-week wait on those. That was the negative, but price-wise, desertcart couldn't be beat for the detectors, especially since I needed 2 CO detectors and 8 smoke detectors. The switch-over from the old detectors to the Kidde detectors was simple and fast. One thing I found out about the CO detectors is that they have a limited lifespan and need to be replaced every 4-5 years. Mine were 6 years old, which is probably why I had to replace the backup batteries about once a month. I had one that would continue to chirp even with a new battery, which is what prompted the replacement in the first place. I really like these new Kidde CO detectors because they have a digital display, which will show the level of CO if there is an alarm, and they will also show you when the battery needs to be replaced.

Has been in over a year and works well. I have this tied in with two smoke alarms and they all go off as they're supposed to when one does.

### ⭐⭐⭐⭐⭐ Great CO detector

### ⭐⭐⭐⭐⭐ Nice Alarm, Easy to Install
*by B***Y on November 4, 2013*

I bought this alarm to replace an older failing alarm that would randomly go off (usually in the middle of the night). I like that this has a digital readout so I can tell if it is a false alarm or if I really do need to evacuate the house. It installed very easily, having a 3-wire hookup for power and connection to other home alarms. It took me all of 15 minutes to screw the back of the alarm to the gang box, connect the wires, twist on the cover, and perform a quick test. I haven't had a false alarm since (crossing my fingers). The only suggestion I have is to provide a place on the front plate where you can place a sticker or write the expiration date of the alarm. This alarm will stop functioning after 7 years and it is easy to forget even as you change the battery. I ended up taking a sharpie and writing the expiration info on the face, so when the alarm goes off in 7 years, I or the new owners of the house will know why.
